Application led December 30,1904. Serial No. 238,978.

To all whom may concern:

Be it known that I, JOHN R. MCGIFFERT, a citizen of the United States, and a resident of Duluth, county of St. Louis, State of Minne- Sota, have invented a new and useful Improvement 'in Lo -Loading Machinesgi' of which the follopving1s a specification, theprinciple ofthe invention bein herein explained and the best mode' in whic I have contemplated a plying that principle, so as to' distin- The said invention consists af (gwn modification ofa log-loading machine s and described in theapplication'forUnited States Letters 4Patent;-y

The said invention consists of Ameans here# means, however," constituting but one of va.-

thereto. Fig. 5 represents a rious mechanical forms in which the-principle of the invention ma be used. l

ln said annexed awin s, Figure 1 represents a erspectiveview p a log-loading' device em od g my-invention Vand mounted upon a iiat og ing-car.` Fig. 2re resents a side elevation o suchl device similar y mount'- ed. 3 represents a .plan view of said de vice. 4 represents, on an enlar ed scale, a sectiona viewof one end of the sliin base of the loader and the derrick-base attached erspectiye view of said base end and derrickase.- Fig.

. 6 representsa detail cross-section taken upon the plane indicated by linef 6, Fig 4,

T e loader' embodying my invention as ,y illustrated in the drawings includes a lower sliding frame havin two side members A A, preferably made of -beams, as shown, which are rovided withu turned ends, whereby the saidpframe may be` rawn upon the surface of the ground or uponthe upper surface of'lo -A ging fiat-cars 'in eitherdirection, These cams or side members are connected and braced in a suitable manner to form a rigid t structure and covered'with a suitablefloormg 2,' preferably steel plates, such construction dfby me even ditte herewith, Serial-Noz--238397L i [base during being specifically described and claimed in ,the above-mentioned copending application.

the side members, is mounted va derrickase B. This base consists of two transverselylocated I-beams b b, arallel with eachother and connected at ,t eir upper surface by means of a top late bi', as shownin 4 and 5. The ends o vthe I-beams restL-upon and are secured to shoes b2, phovided with upturned ends and loosely restihgupon the u per surface of the4 ooring an immediate y above the side members or I-beams of the base, as shown." Passing vertically .through o ,enings in the top an'd bottom plates'and eilanges of the I-beams b b and ae is a king-bolt@ which holds thederrick-base in place and at\the same time permits it to have a` pivotal motion upon the axis of said bolt.

A pivotal bearing is formed by a lower-memb`er l, secured to the top ofthe beams am and formed with a pivot b4, andian upper member b5, secured toV the bottom of the beams b b and formed with'a socket t for receiving the pivot '64, the flooring being cut away at thisv point to provide for the described construction. t

- A series of holes 67 are drilled through the anges of the side members of the base u on arcs having their centers upon the kingolt axis, two o which may be caused to register,

respectively, `with two holes respectively formed in the shoes b2. By means of these registering holes and pins c c the said derrickbase may be fixed in various a ar positions transversely of the sliding base, the said base' being capable of moving upon the kingv bolt axis when the c c are temporarily removed, the shoes sliding upon the loadersuch movement. Upon the front of the forward beam 'b are secured two sockets D for receiving the lower ends of two Y boom members E E, joined at their upper ends, as shown. These lower ends aretpivoted in the sockets'v by means of horizontal pins e e, passin through suitableholesformed inthe socket-p ates and"boom-members.y-Thev e v.

ulpper end of the'boonr, w 'ch is'frmed by t e two boom members E is held by two cables efe, which extendrearwardly'fand have their :extremitigsyfwound u'pontwo Small.. ermetica t0" materielle" rately upon a common shaft e2. These drums are held against rotation bysuitable-ratchet mechanisms and are rovided with disks c2 c2, having peripheral ho es c3 for receiving a bar. By means of a bar and the ratchet mechanism the drums may be separatelyrotated to wind up the cables, and thereby raise the top ofthe boom', so as to cause the boom to swing toward either side of the car, as will be readily understood.

Mounted upon the sliding basawis-'suitable cable-operating mechanism consisting ofv a boiler, an en' ine, and drums operated by the latter. A ca le Fis wound upon one of these drums F and passes under a guiding-'pulley b, mounted upon the pivotal derrick-base B, passin from such guidin -pulleyupwardly aroun a pulley e3, secure'lto the topaif the boom and thence downwardly, las shown. Suitable lov-grippin meansare secured to the end o fb said cale. A second .smaller drumF, fixed to the shaft of drum F has woundupon.it a vcable F, which passes up- Wardly around a block e5 and has attached to its enda sliding Weight f, which4 is guided in a suitable guidewayf, secured to one member of-the boom. This cable is wound upon its drum'in' a direction ,opposite that inwhich th'eqcable F is wound upon its drum, so Vthat -39` and lower the end thereof automatically in a copending application.

' lshown in dott lines.

thesaid weight tends to unwind said cable F manner described in the above-mentioned Wound u on aj third drum vF2 and p'asses v35 vdownwar ly and when in use rearwardly around a guidin drum or roller a, Fig. 2, as At the rear end of thesliding base A, transversely thereof and 1 having its endssecured near the side members, is a chain a. as shown in Figs. 1 and 3.

Two adjacent horizontal uiding-pulleys a3 (1.3

(shown in dotted lines in ig. 3) are also po vided at the rear of the base, being mounted belowthe v:lloror thereof and equidistant from its central line. druni or roller a, as shown in Fig. 3, is inclinedto the axis of the loader, so as tobe substantially atrightangles with the line of l the i ..ble F 5 as it passes from s ueh roller` to they ruiding-pulleys a? a3.

hen `it is desired to move the above-de scribed mechanism rearwardly to the next car, the cable F 5 is passed backwardly between' pulleys a.3 a3 and around a Sheave w", whichis secured in a suitable position to the said next car. From the said sheave the cable is passed tothe chain a', and a hook a6, with which the cable end is provided, is attachcdto one of the links of the chain, as

f shownin full linesin the drawings.

By actuating the cable-operating mechanism it will be. seen that the structure will be drawn. -backwardly, as described. When the hook is attached t0 the middle link of the chain,

the loader is drawn back in a straight line.

A third cable F5 is.

The axis of the guiding W'hen the train, however, is standing upon a curve, the hook maybe caused to engage a link at one side of the middle link, and the structure is thus caused to travel'at an anule conditions. To move the structure forwardly,

the cable F5 is passed to the next forward car around a sheave (not shown) suitably secured thereto and then passes backwardly and is attached to the chain a', as previously described. moved backwai'dly and forwardly, as is described in said copendiiig application.
